Famous Feuds: Gwyneth vs. Martha

The coroner's office has not ruled on the causes of death for two other young people who were in town for the festival.

Anthony Anaya, 25, from Everett, Washington, was reported dead June 21 at the Vdara resort on the Las Vegas Strip. Anaya attended the festival, but it was unknown if his death was linked to it, Clark County Coroner Mike Murphy has said.

Joey Saychack, 21, of Fresno, California, died at a hospital June 25. He was taken there five days earlier after being found unresponsive at a Las Vegas-area house he had rented with a group that was attending the festival, according to Assistant Coroner John Fudenberg.

Nearly 800 people were treated for medical conditions during the event, but only 25 were taken to hospitals for treatment, police said. Organizers advertise a strict anti-drug policy, and police arrested several dozen people on felony drug charges. Previous events have been marred by party drug-related deaths.
